Office Action

§102 §DP
DETAILED ACTION The present application, filed on or after March 16, 2013, is being examined under the first inventor to file provisions of the AIA . Information Disclosure Statement The information disclosure statement (IDS) dated June 9, 2026 was in compliance with the provisions of 37 CFR 1.97 and 1.98. Accordingly, the IDS documents were considered and a signed copy of the 1449 form is attached. Response to Arguments and Amendments Applicant’s arguments and amendments filed June 9, 2026 have been entered. All rejections and objections not explicitly maintained herein are withdrawn. The rejections below constitute the full set of rejections being applied to the instant claims. With respect to the rejections of claims 1, 17 and 36 under 35 USC 102(a)(1) and double patenting, the rejections are withdrawn in view of the claim amendment to cancel all rejected claims. Since the prior art does not teach a compound falling within the amended claim scope, the rejection is withdrawn. Election/Restrictions In accordance with the MPEP, if upon examination of the elected species, no prior art is found that would anticipate or render obvious the instant invention based on the elected species and the claims drawn to the elected species are allowable, the search of the Markush-type claim will be extended (see MPEP 803.02). If prior art is then found that anticipates or renders obvious the non-elected species, the Markush-type claim will be rejected. It should be noted that the prior art search will not be extended unnecessarily to cover all non-elected species. Should Applicant overcome the rejection by amending the claim, the amended claim will be reexamined. Id. The prior art search will be extended to the extent necessary to determine patentability of the Markush-type claim. Id. In the event prior art is found during reexamination that renders obvious or anticipates the amended Markush-type claim, the claim will be rejected and the action made final. Id. As indicated in the previous action, the Examiner searched the claimed invention based on the elected species above, wherein: no prior art was discovered over the elected species and the scope was expanded as described in the previous action. In view of the amendment to overcome the prior art, the scope of the search and examination was again expanded to include the compound described in the rejection herein, having the structure PNG media_image1.png 201 281 media_image1.png Greyscale . Status of the Claims Claims 39-58 are currently pending, all of which have been newly added. Claims 40-57 are withdrawn as being drawn to a non-elected invention and/or species, there being no allowable generic or linking claim. In particular, the newly added claims do not recite the elected species of compound nor the expanded scope of the search and consideration indicated previously, and had they been originally presented would have been withdrawn pursuant to 37 CFR 1.142(b) as described above. Claims 39 and 58 are under consideration to the extent that they are readable on the scope to which the search was extended, indicated above. Matter not embraced by either the elected species or extended scope remains withdrawn from further consideration. It has been determined that the entire scope claimed is not patentable. Claim Rejections - 35 USC § 102 In the event the determination of the status of the application as subject to AIA 35 U.S.C. 102 and 103 (or as subject to pre-AIA 35 U.S.C. 102 and 103) is incorrect, any correction of the statutory basis for the rejection will not be considered a new ground of rejection if the prior art relied upon, and the rationale supporting the rejection, would be the same under either status. The following is a quotation of the appropriate paragraphs of 35 U.S.C. 102 that form the basis for the rejections under this section made in this Office action: A person shall be entitled to a patent unless – (a)(1) the claimed invention was patented, described in a printed publication, or in public use, on sale or otherwise available to the public before the effective filing date of the claimed invention. It is further noted that with respect to each of the rejections below, for the purposes of determining if a reference is a “printed publication” for the purposes of 102(a)(1), MPEP 2128 states the following: PNG media_image2.png 99 480 media_image2.png Greyscale Specifically regarding electronic publications, such as online databases, as prior art the following is noted: PNG media_image3.png 78 750 media_image3.png Greyscale where “prior art disclosures…on an on-line database are considered to be publicly available as of the date the item was publicly posted.” Since the database entries below list the dates that the compounds were entered into the on-line database, the compounds were made publicly available as of those dates in the citation, and the claims are anticipated. Claim(s) 39 and 58 is/are rejected under 35 U.S.C. 102(a)(1) as being anticipated by STN Registry entry for CAS RN 1219426-75-1. Since the entry date represents the date that the compound entered a publicly available database on STN, this represents the date that the compound was made accessible to the public. The prior art compound has the structure PNG media_image1.png 201 281 media_image1.png Greyscale which reads on the claimed Formula (I) where X1 and X2 are each O; R2 is diazine; R4 is methoxyphenyl; R3 is furan; and R1 is benzyl. With respect to the claimed compositions, the prior art teaches the anticipatory compound in solution with unbuffered water. Since the prior art teaches all required limitations of the instant claims, the claims are anticipated. Double Patenting The nonstatutory double patenting rejection is based on a judicially created doctrine grounded in public policy (a policy reflected in the statute) so as to prevent the unjustified or improper timewise extension of the “right to exclude” granted by a patent and to prevent possible harassment by multiple assignees. A nonstatutory obviousness-type double patenting rejection is appropriate where the conflicting claims are not identical, but at least one examined application claim is not patentably distinct from the reference claim(s) because the examined application claim is either anticipated by, or would have been obvious over, the reference claim(s). See, e.g., In re Berg, 140 F.3d 1428, 46 USPQ2d 1226 (Fed. Cir. 1998); In re Goodman, 11 F.3d 1046, 29 USPQ2d 2010 (Fed. Cir. 1993); In re Longi, 759 F.2d 887, 225 USPQ 645 (Fed. Cir. 1985); In re Van Ornum, 686 F.2d 937, 214 USPQ 761 (CCPA 1982); In re Vogel, 422 F.2d 438, 164 USPQ 619 (CCPA 1970); and In re Thorington, 418 F.2d 528, 163 USPQ 644 (CCPA 1969). A timely filed terminal disclaimer in compliance with 37 CFR 1.321(c) or 1.321(d) may be used to overcome an actual or provisional rejection based on a nonstatutory double patenting ground provided the conflicting application or patent either is shown to be commonly owned with this application, or claims an invention made as a result of activities undertaken within the scope of a joint research agreement. Effective January 1, 1994, a registered attorney or agent of record may sign a terminal disclaimer. A terminal disclaimer signed by the assignee must fully comply with 37 CFR 3.73(b). Claims 39 and 58 are rejected under the judicially created doctrine of obviousness-type double patenting as being unpatentable over claims 1-13 and 15-18 of US Patent 9,975,885. An obviousness-type double patenting rejection is appropriate where the conflicting claims are not identical, but an examined application claim is not patentably distinct from the reference claim(s) because the examined claim is either anticipated by, or would have been obvious over, the reference claim(s). See, e.g., In re Berg, 140 F.3d 1428, 46 USPQ2d 1226 (Fed. Cir. 1998); In re Goodman, 11 F.3d 1046, 29 USPQ2d 2010 (Fed. Cir. 1993); In re Longi, 759 F.2d 887, 225 USPQ 645 (Fed. Cir. 1985). Although the conflicting claims are not identical, they are not patentably distinct from each other because the compound and compositions used in the instantly claimed methods are anticipated by those in the patented claims. In particular, the conflicting claims recite compounds of the formula PNG media_image4.png 158 154 media_image4.png Greyscale , pharmaceutical compositions (claim 15), and methods of treatment comprising administration of the compound (claims 16-18). The conflicting claims overlap with the instant claims where R4 is phenyl, R2 is imidazole and R1 is benzyl. By way of particular examples, the patent teaches many compounds falling within the claimed genus which anticipate the instantly claimed species. For example, compound 59: PNG media_image5.png 183 157 media_image5.png Greyscale PNG media_image6.png 114 416 media_image6.png Greyscale . Since the patented claims encompass all the required features of the instant claims, a double patenting rejection is appropriate. Conclusion No claims are allowed.
